With all due respect, and I really mean that -- not just sticking it in to look cool and soften what's next -- I am not so sure the purpose of this site is served by just laughing at a beginner and not explaining to the beginner what you think is funny. I mean, isn't one purpose here to educate.
I suspect that there weren't too many folks hatched from the Great IT Egg with a head full of all the IT World's knowledge. Maybe I mean everybody was a beginner and maybe picked up bits and pieces of knowledge from mistakes because somebody didn't just chuckle, they also did a bit of teaching.
I'm not stating that there's any harm in snickering at the doings of some beginners or rookies, but throw in a little knowledge once your done snickering and you might just be helping the IT World in some form. And in some cases you might also be promoting some good will in the community where you reside at the moment. I mean the Net community where the chuckling producing incident takes place. Yes, some of us reside in many Net communities, but still ... Well, I suppose I've written enough, haven't I? Probably too much.
I just feel uncomfortable when folks snicker at rookies and don't let the rookies in on the joke.
In my first profession, aviation, not teaching rookies what their mistakes were could cost lives. That attitude and manner of conducting business has never left my bones.
